Latest Patents
Marnie Dunsmore holds a patent for a "Polar modulation transmitter with envelope modulator path switching." This invention includes methods and apparatus for controlling power in a polar modulation transmitter. The exemplary polar modulation transmitter features a radio frequency power amplifier (RF PA), a phase path with circuitry that generates a constant amplitude phase modulated signal, and an amplitude path that includes an envelope modulator circuit with first and second envelope modulation paths. The RF phase modulated signal is applied to the RF input of the RF PA, while an envelope modulated power supply signal generated by a selected envelope modulation path is coupled to the power supply input of the RF PA. The second envelope modulation path is selected when the power required by the RF PA is below a predetermined power level, while the first path is chosen when the power requirement exceeds that level. This innovation is crucial for optimizing power usage in communication systems.
